6 Critical Factors Contributing to Commercial Truck Accidents in the USA

Commercial truck accidents involve complex variables due to vehicle scale and federal regulations. Understanding the primary causes is essential for road safety and legal liability assessment.

The 6 Most Common Factors That Lead to Truck Accidents

1. Distracted Driving and HOS Violations

Distraction remains a leading cause of collisions. Beyond mobile phone use, violations of Hours of Service (HOS) regulations often lead to fatigue, which functions similarly to cognitive distraction. Federal law strictly limits driving hours to prevent exhaustion-related errors.

2. Impaired Operation and Health Stress

Impairment in commercial driving is not limited to controlled substances. High stress levels and undiagnosed health conditions (like sleep apnea) can significantly affect a driver’s reaction time and decision-making capabilities on the road.

3. Excessive Speed and Stopping Distance

A fully loaded commercial truck (up to 80,000 lbs) requires a stopping distance nearly double of a passenger vehicle. Overspeeding, often driven by strict delivery deadlines, reduces the margin for emergency braking, especially in heavy traffic.

4. Cargo Dislodgement and Weight Distribution

Improperly secured cargo can shift during transit, altering the truck's center of gravity. This instability increases the risk of rollovers during sharp turns. Key issues include:

  • Overloaded trailers exceeding federal weight limits.
  • Unbalanced loads causing steering mechanical stress.

5. Infrastructure and Environmental Hazards

Inadequate road maintenance, such as poor lighting or insufficient merging lanes in construction zones, poses higher risks for large vehicles. Adverse weather (fog, ice, or heavy rain) drastically reduces visibility and tire traction on asphalt.

6. Driver Qualification and Training Deficits

The trucking industry faces a shortage of experienced operators. Inadequate training in handling specialized equipment or navigating mountainous terrain leads to errors in judgment, particularly regarding speed control on steep descents.
